“Thank you very much for pointing out the vulnerability. The security issue you identified could have potentially allowed outside parties to access some of Honda’s cloud-based data that consisted of information related to our employees and their computers. We investigated the system’s access logs and found no signs of data download by any third parties. At this moment, there is no evidence that data was leaked, excluding the screenshots taken by you. We will take appropriate actions by relevant laws and regulations, and will continue to work on proactive security measures to prevent similar incidents in the future.”
